S-3A Data Unavailability (14 November 2017)

16 Nov 2017

Due to a Ground Segment anomaly on 14 November 2017, some data were lost for Sentinel-3A . The absolute sensing orbit involved were 9079 and 9080, i.e. relative orbits 251 and 252 of cycle 24.

This impacted data availability from instruments for the following UTC time periods:

OLCI - From 11:32:12 to 11:41:12.

SLSTR - From 12:05:12 to 12:49:11.

SRAL - From 11:48:49 to 12:18:49.

Please note that products partially covering these sensing times might be degraded or missing.

Collaborative users are informed that OVH is facing a major electrical problem at their data centre in Strasbourg where ColHub Node 2 is running. ColHub Node 2 service has been down since 6:19 UTC of the 9th of November 2017.
Investigation of the problem with ERDF (the national company in charge of the electrical network) is ongoing.
We apologise for the inconvenience this may cause.

Sentinel-2B MSI decontamination sequence between 24 and 27 November 2017

09 Nov 2017

A routine decontamination activity of the Sentinel-2B MSI is planned over a continuous period of approximately 24 hours from 06:15 UTC on 25 November and 05:40 UTC on 26 November (corresponding approximately to absolute orbits of 3764 and 3777).

During this time period, no MSI acquisition will take place.

Correlated calibration activities will be performed before and after the decontamination activity and will also affect the acquisition plan from 06:28 UTC on 24 November to 06:40 UTC on 27 November.

Collaborative users are informed that the power outage occurred on OVH infrastructure (see news) hosting the ColHub Node 2 service has been solved.
The ColHub Node 2 access point has experienced a downtime from 6:19 UTC to 13:28 UTC of the 9th of November 2017.
The ColHub Node 1 access point was not affected by the issue.
Products publication is gradually restored to nominal.
We apologize for the inconvenience that this may have caused.

S-3A Data Unavailability (August 24th/ September 11th and 13th, 2017)

08 Nov 2017

Due to Radio Frequency Interference events with other spacecraft on 24 August and 11 and 13 September 2017, some data was lost for Sentinel-3A during the downlink orbits 7914, 8172 and 8194.

This impacted the data from the instruments for the following UTC time periods:

OLCI - From 17:16:21 to 17:19:21 on 24 August. From 19:25:00 to 19:28:00 on 11 September. And from 07:59:43 to 08:02:43 on 13 September.

SLSTR - From 08:17:43 to 08:20:43 on 13 September.

SRAL - From 20:17:04 to 20:27:04 on 11 September. And from 08:04:38 to 08:14:38 on 13 September.

Please note that products covering these sensing times might be degraded or missing.
